I am totally new to working with Maven in Eclipse. I am using the latest verion of Eclipse (Kepler). According other posts, as well as Eclipse's help page http://help.eclipse.org/kepler/index.jsp?topic=//org.eclipse.platform.doc.user/tasks/tasks-127.htm , I am supposed to try to install new software within Eclipse IDE.
However, when I try to Add Eclipse's recommended m2e release, Eclipse gives me an error:
Unable to read repository at http://download.eclipse.org/technology/m2e/releases.
download.eclipse[...]releases is not a valid repository location.
Essentially I run into the same problem no matter which approach I take outlined on the Eclipse help page. Is there some other/better way to integrate Maven with Eclipse? Are there steps I should have taken before this? All I have done so far is install Eclipse. How can I successfully get Maven running?
EDIT: Now I am using Java EE and still run into problems when making a Maven project. I get a "Could not resolve archetype error" could this be because I'm behind a proxy?
Most convenient option:
The reason you're getting that error is because that repo is deprecated, and it has been moved. Example of how the new repo looks:
http://download.eclipse.org/technology/m2e/releases/1.0/1.0.0.20110607-2117
Copy that in the Install New Software view, and you will see that it works.
Other options:
Install the Maven Integration from Eclipse Marketplace (Help -> Eclipse Marketplace)
Download the EE version of Kepler (comes with m2e)
Choose your own release (bottom of the page) and use the Install New Software view.
I had the same issue here and the above answer didnt work for me. Although Maven is installed I cane update my dependencies on my folder the way I used to be able to do on Juno. What I did was used the pom.xml from my current project and pasted it into the pom of my new project I created specifically in Eclipse using new project->Maven.
This was eclipse knows its a Maven project and allows my all the benefits of being one.
To install maven properly for eclipse you should set the correct repos as follow:
Help=>install=>
then work with
http://download.eclipse.org/releases/
example of eclipse version : mars or kepler ..

I am working on Eclipse plugin. At the beginning exporting of it worked fine but I guess that after updating Eclipse it broke down. Eclipse started to mentioned that I have uninstalled some equinox packages. It took time till I understood that version of Eclipse made a problems and I reinstalled older version of Eclipse. Now I am again able to run sample environment with plugin but I still am not able to export plugin. In export form where I need to select deployable plugin and/or fragments I don't have listed anything. From what I found I understand that it might be problem with importing project in Eclipse as it might not remove information that project is external and thus not listing as project that could be exported. But I did not find any way to prove this case.
Is there anybody having any idea how to solve this kind of issue?
The Console view does not show any output when the Maven is configured to external Maven installation in Eclipse.
Please refer to the screenshots for more details.
The Console is displayed when Maven → Installations is configured for EMBEDDED Maven.
My external Maven version: 3.5.0, Eclipse Luna.
TIA
Apparently you're using Maven's brand new v3.5.0 that's just three weeks old. I don't know whether the m2e Eclipse plugin has been updated to support it already. I performed Help → Check for Updates in Eclipse and there wasn't any.
I'd try Maven's previous v3.3.9 which I experienced to be stable for 1.5 years now to see whether it works with that.
I'm new to Java EE development and I heard that If I have to learn the Java EE then the Spring MVC is best choice to learn and get Command of.
After downloading STS 3.6 bundle I'm having some troubles/issues in creating Maven Project. My STEPS are
1- Create new project
2- Error Dialog
It appears that you either don't have Maven installed, or your IDE is not aware of the installation. For the former problem, have a look here. For the latter problem, view this page for IDE you are using:
Eclipse
I would also like to recommend to get started with Spring using the Spring Tool Suite by using Spring Boot and the guides at http://spring.io/guides. You can import those guides directly into STS and start from there.
I also face with this thing too, but I found a solution that just update Maven project by right click on project -> Maven-> Update Project... or (Alt+F5) then check on force to update as image below :
It works perfect for me.
NOTE** internet connection is required
I have created project using Spring Tool Suite IDE, with below navigation.
New -> Spring Starter Project
But outcome was always simple maven M2 project with error symbol.
After project build completion I have updated maven project with option "Force Update of Snapshots/Release".
It turned my project M2 project into M2S Project
Thanks
I installed JUNO Eclipse and then wanted to get the maven plugin for eclipse. After some searching I got to know that I can install the plugin using eclipse market place. So I searched the plugin and installed it successfully but when I restarted eclipse, I cannot see Maven option when I right click on any project. When I click on WINDOWS--> PREFERENCES , I can see the Maven option there. It means, maven got installed but not sure if completely.
I reinstalled it again but still no luck. Can anyone help?
FYI, I am using maven 3.0.4
If your project is still a standard Java project, then you have to enable Maven for this project. You can do this by right-clicking on the project, then choose Configure -> Convert to Maven project. Then you have to type group id, artifact id etc. and the pom.xml is created for you.
You need to make sure you have installed the Java JDK and add it to the Preferences -> Java -> Installed JREs.
I have an existing Dynamic Web Project in Eclipse Indigo and the m2e plugin installed. In another version of my eclipse setup that I dont quite remember (my hdd crashed) I could just right click on the project -> Maven -> Enable Dependency Management.
This menu is gone for my Dynamic Web Project in my current eclipse version. Whats the way to go now? I tried right click on the project folder -> configure -> convert to maven project but that fails with errors.
M2Eclipse has migrated to an Eclipse project from Sonatype called m2e. Therefore in you Eclipse Indigo you have installed m2e whereas your old Maven projects in the older Eclipse version were created with M2Eclipse according to your right-click description. Now under normal circomstances everything should be working flawlessly and we wouldn't have this discussion. Unfortunately with the move of the project the namespace has changed from org.maven.ide.eclipse to org.eclipse.m2e.core and old Maven projects created with M2Eclipse are not immediately recognised as Maven projects in m2e. Here's a description of how to migrate your projects accordingly.
Erik, importing an existing maven project would let m2e discover and propose you to install m2e-wtp, the Maven Integration for Eclipse WTP plugin. Since you're starting from scratch, you should install m2e-wtp yourself (see https://github.com/sonatype/m2eclipse-wtp/wiki).
Now in order to quickstart a new mavenized web project, you should go to the "New Project" menu and choose new Maven project.
At this point, either you choose to create a "simple" project, in which case you need to select the "war" packaging on the following screen, or use a maven archetype, which will quickstart a new preconfigured web project, with the flavor you want (jsf, spring ...). The m2e-wtp wiki has links to help you get started.
Note : at this point Eclipse to Maven conversion is pretty much inexistant (only creates a bare pom.xml), that's why I recommend to create a maven project first. Hopefully, this should get better in the next m2e 1.1 (June 2012)
